GEORGE M. GRANGER, OF MEMPHIS, MICHIGAN.

Letters Patent No. 90,942, (la-ted June 8, 1869.

WASHJBOILER.

The Schedule referred to in these Letters Patent and making part of the same.

.marked thereon, and being a part of this specification.

Sheet 1 is a perspective vertical section of the washing-steamer.

- Sheet 2 is a sectional plan view of the same, on line a z of sheet 1, showing particularly the tubes or channels through which the water passes back into the cradle.

Like letters denote like parts in each of said sheets.

The nature of this invention relates to an improvement in that class of boilers which are employed in cleansing clothes; and

It consists in a boiler, inside of which is placed a cradle or receptacle for the clothes, said cradle being constructed either of slats, wire, or perforated metal.

The inyention also consists in an annular trough, extending around the outside of the boiler, and so arranged that all the water which may boil over the top of the boiler will be prevented from falling, except into said trough, whence, by proper channels, it is returned to the inner side of the boiler. V

A, in the drawings, represents a boiler, of any ordinary form, made from sheet-metal.

B is the cradle or receptacle for the holding of the clothes while being cleansed.

This cradle, which may be made of slats, wire-work, perforated sheet-metal, or other appropriate material, should be made conical in shape, its base being of a suitable size to allow the turned flange O to rest upon the top roll 1) of the boiler.

It will be seen that this cradle, when in position, is

an inverted cone, with its apex flattened.

E is an annular trough extending around the outside of the boilerA, and soldered or otherwise secured thereto, in such a manner as to catch all water that may boil over the top of the boiler.

This water then passes through the openings E into the channels or tubes G, and thence through open ings H, into the interior of the cradle or receptacle B,

whence, by its own gravity, it falls through the perforations in the bottom of said cradle, to be again used. I are hooks, bynicans of which a proper cover may be secured upon the top of the boiler and cradle.

Fill the boiler with water, so that the bottom of the cradle will be covered to about the depth of an inch.

Then fill said cradle or receptacle with the clothes which it is desired to cleanse, secure the cover in place, and setthe boiler over a fire.

The cover being secured by the hooks I, allows steam to be made at a higher pressure than cauordinarily be attained in boilers for a like purpose. This steam, rising upward in the space between the walls of the boilerand the cradle, will be forced through the perforations in the metal of which said cradle is formed, and through the clothes within it, thereby cleansing them more thoroughly than can be done by the usual methods.

' The steam, as it condenses, falls downward into the boiler again, where it is again converted into steam, and the process is continued until the clothes are cleansed.

Condensed steam or water, boiling-over the top of the boiler, is caught by the trough E, and returned, as hereinbefore described, to the interior of the cradle, through the channels and openings.

The lower openings, H, open directlyinto said cradle, for the reason, that did they open into the boiler, the pressure of steam would prevent the water from returning through the channels.

What I claim as my invention, and desire to secure by Letters Iatent, is-

The channels or tubes G, with openings F and H, in combination with the cradle B and hook I, and any suitable cover and boiler, when constructed, arranged, and operating substantially as aforesaid.
